Looks good to me, except for minor formatting nit.

test/jdk/javax/swing/regtesthelpers/Util.java line 150:

Suggestion:

        return findComponent((Container) parent,
                             c -> c.getClass()
                                   .getName()
                                   .contains(className));

Correct alignment.
